I do not think that anyone here would dispute that a DPF is not fit for purpose, but its the best solution the manufacturers can come up with

It's a problem of our own making, 30 years ago motorist realised that diesel fuel was cheaper to buy and diesel vehicles did more miles per gallon. Once the sales of diesel vehicles took off manufacturers such as BMW, Mercedes, Honda, Nissan etc realised that if they did not respond to demand they would loose billions in lost sales to rivals

Along the way Governments have told them to clean up their emissions year on year until we have now reached this point and ended up with an engine that is over designed and engineered, with anti pollution devices bolted on to comply with lower emissions......at the end of the day it's still an old oil burner and I think we have now reached the clean up limit with Euro 6.....also mega expensive to maintain after a couple of years (DPF's, Turbo's, Fuel Pumps etc)

Will the manufacturers want to invest in Euro 7 diesels or are we going to see a return to cleaner more efficient petrol and electric over the next 30 years

Formula 1 back soon with 1.6 V6 petrol engines with some assistance with electric drive at the wheels, this has got to be the way forward, smaller engines, more power and less pollution

Manufacturers have invested millions in diesel technology and may be reluctant to give it up, but one manufacturer will rise to the challenge and and give us a decent size car with a smaller petrol engine and possible electric assisted drive with ultra low emissions, the rest will follow........why persist with oil burners? lets leave diesel fuel where in belongs......in the Farm Yard
